We just learned about the Freyella Elegans.
Another type of starfish is Heliaster microbrachius.
This starfish grows to be about 4 inches, and can have lots more arms than most starfish, and also a bigger disc for the center of their body.
They can be purple, black, yellow or white, and they live in the Pacific Ocean near Mexico.
